Definitions
- the invention relates to a gas valve unit for adjusting a gas burner of a gas appliance, in particular a gas cooking appliance, supplied gas volume flow, wherein the gas valve unit comprises a valve housing and an actuating shaft for adjusting an opening cross-section of the gas valve unit and an additional shut-off valve, and wherein a movement of the actuating shaft by means of a linearly displaceable Connecting element is transferable to the shut-off valve.
- Gas valve units of the type mentioned with a shut-off valve are often referred to as secure gas valves.
- On an operating section of the gas valve unit is usually attached a rotary knob, which can be accessed manually by an operator of the gas cooking appliance.
- the setting of the opening cross section of the gas valve unit is usually carried out by turning the actuating shaft.
- the shut-off valve can be opened by the operator by axially moving the actuating shaft by pressing on the rotary knob.
- the axial movement of the actuating shaft is transmitted to a linearly displaceable connecting element.
- This transmission of the movement of the actuating shaft to the connecting element can be done directly or indirectly, for example via a device for deflecting the direction of movement.
- the connecting element is directly or indirectly in contact with a shut-off element of the shut-off valve. With an axial movement of the connecting element in the direction of the shut-off this can be lifted from a valve seat and thereby the shut-off valve can be opened.
- the shut-off valve further has a magnetic unit with which the shut-off element can be held in the open position after the shut-off was manually brought by pressing the valve shaft in this open position.
- the magnet unit usually contains a wound coil which is connected to a thermocouple arranged in the region of a gas burner. The electrical voltage generated by the thermocouple causes a current flow through the coil of the magnet unit and thus generates a magnetic force that keeps the shut-off valve open as long as a gas flame burns on the gas burner. When the gas flame goes out, the shut-off valve closes automatically and can only be reopened manually by pressing the actuating shaft.
- shut-off member can be moved by pushing the operating shaft in the opening direction until it is applied to the magnet unit. If the depression of the actuating shaft takes place with great force, this can lead to a deformation of the shut-off element, which can impair the function of the shut-off valve. In particular, it is possible that the deformed shut-off element can no longer be held in the open position by the magnet unit because there is an excessively large air gap between the shut-off element and the magnet unit as a result of the deformation.
- the present invention has for its object to provide a gas valve unit available, in which the function of the shut-off valve is ensured permanently safe.
- the connecting element has at least one spring.
- the spring yields and thus prevents damage to components of the shut-off valve.
- the spring is designed so that normal actuating forces are transmitted by the spring.
- the spring ensures that when the operating shaft is pressed by the operator, the shut-off valve is opened so far that the shut-off element can then be kept open automatically, for example by means of a magnet unit supplied with power by a thermocouple.
- the term "spring" refers to any force-dependent elementally variable and / or variable-length element, irrespective of the material and / or of the shape of the element, for example wound metal springs or molded plastic springs.
- the connecting element is suitable for transmitting compressive forces.
- compressive force is understood to mean a linearly acting force.
- the spring of the connecting element is expediently designed as a compression spring.
- the compression spring changes its length in the case of a linear force action.
- the spring of the connecting element is designed as a helical spring.
- the coil spring has a constant or varying radius of curvature.
- the coil spring has a cylindrical shape.
- the diameter of the coil spring is constant over the spring length.
- the radius of curvature varies along the length of the coil spring such that the coil spring has a smaller diameter at one location than at another location spaced axially from the first location.
- the connecting element is guided in a region with the maximum radius of curvature of the helical spring in the valve housing.
- the entire length of the coil spring is the area with the maximum radius of curvature.
- the area with the maximum radius of curvature is the widest point of the connecting element at all.
- the shut-off element is biased by a closing spring in the closed position. This ensures that the shut-off valve is always closed in the rest position. By manually pressing the actuating shaft, the shut-off valve can be opened against the force of the closing spring. In the closed position, the shut-off element rests on a valve seat of the shut-off valve and thus prevents the flow of gas through the gas valve unit.
- a spring constant of the spring of the connecting element is greater than a spring constant of the closing spring. Pressing the actuating shaft therefore leads initially primarily to a compression of the closing spring and thus to an opening of the shut-off valve. Only when the shut-off valve is opened to the maximum and the shut-off element abuts against an end stop, the force acting on the connecting element increases, whereby the spring of the connecting element compresses reinforced. The maximum force acting on the shut-off force is thus limited by the spring of the connecting element.
- a deflection device which transmits an axial movement of the actuating shaft in a substantially perpendicular axial movement of the connecting element.
- a deflection device is required in particular when the size of the gas valve unit is limited in the longitudinal direction of the actuating shaft.
- the deflection device has a first sliding element, which is arranged on the actuating shaft in the region of an operating section opposite end of the actuating shaft.
- the operating portion of the actuating shaft is the portion on which, for example, a rotary knob can be plugged.
- the operating section opposite end of the actuating shaft is located inside the housing of the gas valve unit.
- the first sliding element is designed as a first conical element, such that a tip of the first conical element points away from the operating section of the actuating shaft.
- the embodiment of the sliding element as a conical element has the advantage that the spatial extent of the sliding element is independent of the rotational position of the actuating shaft.
- the deflection device has a second sliding element, which is in contact with the first sliding element at least during a pressing of the actuating shaft.
- the second sliding element is designed as a second conical element whose central axis is arranged substantially perpendicular to the actuating shaft and whose tip points in the direction of the first sliding element.
- the second sliding element is preferably arranged on the end of the connecting element facing the actuating shaft. An axial movement of the second sliding element thereby automatically causes an axial movement of the connecting element.
- the connecting element has at least one section in which a spring wire is aligned parallel to a direction of movement of the connecting element. In this section, the spring wire is loaded in the longitudinal direction and therefore has no spring action in the loading direction. It is a section of the same spring wire from which the coil spring is formed.
- the second sliding element is fastened to the spring wire, preferably on the section of the spring wire parallel to the direction of movement of the connecting element.
- the gas valve unit for adjusting the opening cross-section at least two open-close valves and at least two throttle bodies, each having at least one throttle opening, which are traversed in dependence on the switching position of the open-close valves with gas.
- the adjustment of the opening cross-section is thus carried out by targeted opening and closing of the open-close valves. This is done by turning the actuating shaft.
- a permanent magnet may be provided which is moved across the open-close valves.
- the open-close valve which is located directly in the area of the permanent magnet, is opened by magnetic force.
- the shut-off valve is opened by pressing the actuating shaft by means of a mechanical force. Subsequently, it can be kept open by means of an electromagnetic force, for example as a result of the voltage generated by a thermocouple for flame monitoring.

- FIG. 12 shows the gas valve unit in a sectional view.
- Figures 1 to 3 show the switching arrangement of the on-off valves 3 (3.1 to 3.5) and the throttle bodies 4 (4.1 to 4.5) of the gas valve unit. However, the shut-off valve according to the invention and the connecting element are not shown here.
- a gas inlet 1 with which the gas valve unit is connected for example to a main gas line of a gas cooking appliance.
- the combustion gas provided with a constant pressure of, for example, 20 millibar or 50 millibar.
- a gas outlet 2 of the gas valve unit a leading example, to a gas burner of the gas cooking appliance gas line is connected.
- the gas inlet 1 is connected via a gas inlet space 9 of the gas valve unit with the input side of the present in the present embodiment, five open-to-valves 3 (3.1 to 3.5).
- the on-off valves 3 By opening the on-off valves 3, the gas inlet 1 is in each case connected to a specific section of a throttle section 5, into which the gas flows via the open on-off valve 3.
- the throttle section 5 comprises an inlet section 7, into which the first open-close valve 3.1 opens.
- the further open-close valves 3.2 to 3.5 each open into a connecting section 6 (6.1 to 6.4) of the throttle section 5.
- the transition between the input section 7 and the first connecting section 6.1, and the transitions between two adjacent of the connecting sections 6.1 to 6.4 are respectively formed by a throttle 4 (4.1 to 4.5).
- the last restrictor 4.5 connects the last connecting section 6.4 with the gas outlet 2.
- the throttling points 4.1 to 4.5 have a sequentially increasing opening cross-section.
- the flow cross section of the last throttle point 4.5 may be chosen so large that the last throttle point 4.5 has virtually no throttle function.
- the gas flows from the gas inlet space 9 directly into the first connecting section 6.1 and from there via the throttling points 4.2 to 4.5 to the gas outlet 2.
- the gas flowing to the gas outlet 2 bypasses due to the open on-off Valve 3.2 the first restriction 4.1.
- the gas volume flow in the switching position according to FIG. 2 is therefore greater than the gas volume flow in the switching position according to FIG. 1.
- the gas flow to the first connecting section 6.1 takes place virtually exclusively via the second on-off valve 3.2. Due to the open-close valves 3.1 and 3.2 prevails in the input section 7, the same pressure level as in the first connection section 6.1. Therefore virtually no gas flows from the inlet section 7 via the first throttle point 4.1 into the first connecting section 6.1.
- the total gas flow flowing through the gas valve unit therefore practically does not change when the permanent magnet 8 is moved further to the right in the drawing and thereby the first on-off valve 3.1 is closed when the second open-close valve 3.2 is open.
- FIG 3 shows the schematic circuit arrangement of the gas valve unit in the maximum open position.
- the permanent magnet 8 is in its end position on the right side in the drawing.
- the last open-close valve 3.5 is opened at this position of the permanent magnet 8.
- This last restrictor 4.5 may have such a large flow cross-section that virtually no throttling of the gas flow occurs and the gas can flow through the gas valve unit virtually unthrottled.
- Figure 4 shows schematically a structural design of a gas valve unit with a switching arrangement according to figure 1 to 3. The shut-off valve according to the invention is also not shown here.
- valve body 20 in which the gas inlet 1 of the gas valve unit is designed. Inside the valve body 20 is a gas inlet space 9 connected to the gas inlet 1.
- Shut-off bodies 10 of the open-close valves 3 are guided in the valve body 20, such that they can move up and down in the drawing.
- Each shut-off body 10 is biased by a spring 11 in the drawing below.
- the springs 11 press the shut-off body on a valve sealing plate 12, so that the shut-off body 10 in the valve sealing plate 12 openings 12a seal gas-tight.
- a pressure plate 13 is arranged, with openings 13 a, which correspond to the openings 12 a in the valve sealing plate 12.
- the openings 13a in the pressure plate 13 open into openings 14a in a first gas distribution plate 14.
- a throttle plate 15 having a plurality of throttle openings 18.
- Each of the throttle points 4.1 to 4.4 is formed by two throttle openings 18 .
- the two throttle openings 18 belonging to a throttle point 4.1 to 4.4 are connected to one another in each case by means of the openings 16a in a second gas distribution plate 16.
- the openings 14a in the first gas distribution plate however, connect the adjacent throttle openings 18 of two adjacent throttle points 4.1 to 4.5.
- the last orifice 4.5 consists of only one throttle opening 18, which opens via a corresponding opening 16a in the second gas distribution plate 16 in the gas outlet 2 of the gas valve unit.

- the open-close valves 3, which are located directly above the permanent magnet 8 are opened by the magnetic force of the permanent magnet 8.
- a knob which can be grasped directly by the operator can be attached.
- a cover 30 is formed, in which, from bottom to top, the valve sealing plate 12, the pressure plate 13, the first gas distribution plate 14, the throttle plate 15 and the second gas distribution plate 16 are arranged.

- the first sliding element 41 is in contact with a second sliding element 42, which is coupled via a connecting element 45 to a valve body of the shut-off valve.
- Both sliding elements 41, 42 are of conical bodies educated.
- a third conical body 43 serves as part of a coupling device 26, with which a rotational movement of the actuating shaft 31 is transmitted to the actuator 25.
- the coupling device 26 essentially consists of a driver 27, which engages in a slot-shaped recess 28. In the position shown in Figure 5, the gas valve unit is in the fully closed position.
- the rotational position of the actuating shaft 31 is selected such that the permanent magnet 8 is not below an open-close valve 3 and thus all open-close valves 3 are closed.
- the actuating shaft 31 is not pressed in the axial direction.
- the second slider 42 is in a left stop position. Due to the shape of the first sliding member 41 as a conical body has an exclusive rotational movement of the actuating shaft 31 and thus of the first sliding member 41 has no influence on the position of the second sliding member 42.
- the lower end of the actuating shaft 31 is also of a (third) conical Body 43 formed.
- shut-off valve 40 opens and the valve housing 20 fills with gas.

- the shut-off valve 40 can thereby be traversed by gas.
- the connecting element 45 is designed as a spring.
- the connecting element 45 forming the spring 45b is designed substantially stiffer than the closing spring 51 of the check valve 40.
- the formation of the connecting element 45 as a spring 45b is used in particular to avoid damage to the check valve 40 when pressed onto the actuating shaft 31 with excessively large force ,
- FIG. 12 shows a gas valve unit according to the invention in cross section. Shown are the gas inlet 1, which opens directly into the shut-off valve 40. Of the check valve 40 in particular the shut-off body 10, the closing spring 51 and the magnet unit 50 can be seen.
